The title compound, m/e=362.3 ([M−H]−), was produced in analogy with example 1, steps 3 and 4. Thus, 3-pyridinenonanoic acid (U.S. Pat. No. 4,632,925) was coupled in step 3 with (R)-3-amino-4-dimethylamino-butyric acid benzyl ester dihydrochloride to produce (R)-4-dimethylamino-3-(9-pyridin-3-yl-nonanoylamino)-butyric acid benzyl ester, which was hydrogenated in step 4.
